IMU is equipped with six DoF sensor to measure slow and fast motion

Tue, Jul 25, 2023

IMUs (inertial measurement units) from Epson now include the M-G370G, which has been added to the company’s portfolio.

It allows users to select an accelerometer output range of either ±8G or ±16G and offers 0.05 per cent non-linearity of the full scale range of the gyroscopic sensor. In this way, the M-G370G IMU measure all types of motion, from slow to fast, said Epson.

The IMU is compact, with dimensions of 24 x 24 x 10mm³ and is backwards compatible with the M-G330 and M-G366, M-G370 and M-G370S IMUs which will sharply reduce development costs and evaluation time, noted Epson.

It has a low current consumption of 16mA, making it suitable for vibration damping for cameras and antennas, unmanned vehicles (industrial drones, terrestrial vehicles, sea probes), vibration, angle, trajectory measurement of industrial equipment and for navigation systems (GNSS, INS4, high-precision locators).

Epson will exhibit the M-G370G at Maintenance and Resilience Tokyo 2023 26 to 28 July, at Tokyo Big Sight.

First launched in 2011, Epson’s IMUs have been used in an array of customer applications, from precision agriculture (GNSS2) and industrial drones to camera and antenna platform vibration control and stabilization, earning an excellent reputation for outstanding performance and quality. Epson has a full range of IMUs, from basic models to high-spec models. All are based on a platform that measures about one inch along the sides, the standard form factor for IMUs.

The M-G370G will enter volume production this month.

Small and versatile geo-location tracker has temperature sensor

Tue, Jul 25, 2023

Netherlands based SkyNet IoT claims that the LoRaWAN NanoTag is the smallest, most affordable, and most versatile Geo-location tracker and temperature sensor with international LoRaWAN coverage.

Suitable for remote temperature monitoring, the LoRaWAN NanoTag provides geo-tracking and temperature monitoring in a miniature format of just 98 x 130 x 1.5mm.

The NanoTag sticker is a compact, thin, cost-effective temperature sensor with a resolution of 0.1 degrees C. Described as the smallest, most affordable, and most versatile geo-location tracker and temperature sensor in the world, the NanoTag can be used for temperature conditioned transport and logistics as well as for monitoring temperatures in heating and cooling installations.

It has adjustable measurement intervals to provide users with full control. The measurement intervals can be adjusted remotely, allowing users to receive the necessary data exactly when needed. With a measurement interval of, for example, 15 minutes, the NanoTag has a lifespan of several years. This makes it suitable for long term tracking and/or temperature monitoring projects.

The NanoTags are connected to the SkyNet IoT LoRaWAN network as standard. This network provides maximum international coverage and offers secondary network roaming across various connected networks. This is something individual LoRaWAN providers do not offer, said SkyNet IoT. With more than a million connected LoRaWAN gateways from various network providers worldwide, SkyNet IoT claims to offer the maximum coverage and redundancy in LoRaWAN connectivity on the market.

LoRaWAN is the fast-growing IoT standard for sensor connectivity, characterised by its long-distance communication performance with low energy consumption and deep indoor range. Unlike individual LoRaWAN providers, the SkyNet IoT network offers roaming across various connected networks, providing maximum international connectivity.

Although the SkyNet IoT network offers maximum coverage, there may be areas where the (indoor) coverage is absent or limited or where accurate Geo-Location is desirable, said the company. In such cases, the SkyNet IoT network can be expanded to unlock a (larger) (indoor) area and/or to achieve accurate Geo-Location. Although SkyNet IoT offers maximum international coverage, the NanoTags are bound to the frequency bands of specific continents, said the company. For this reason, SkyLab can provide a multi-band solution if required.

The LoRaWAN NanoTag is a versatile tool for refrigerated transport, where temperature and location monitoring are crucial when transporting medicines, organs, chemicals, or fresh products like vegetables and fruit.

SkyLab B.V. offers the NanoTag in a complete package with a customer IoT Dashboard and the SkyNet IoT network, for a one-time fee of $60 each (the price is lower for large quantities). This all-in package contains no hidden costs and is valid for the full lifespan of the NanoTag. Demo NanoTags are available for evaluation.

Compact LTE-M / NB-IoT module by u-blox has 2G fallback capability

Wed, Jul 19, 2023

The LEXI-R4 is a compact module that has been customised for applications where space is limited. It has dimensions of 16 x 16mm and supports all LTE-M and NB-IoT bands with an RF output power of 23dBm. It also has the possibility to operate on a 2G network. Typical applications are small asset trackers, such as pet and personal trackers, micromobility devices and luggage tags. It is also able to encompass larger applications, such as alarm systems, vending machines and stolen vehicle recovery systems, advised u-blox.

The u-blox LEXI-R4’s compact dimensions are a 40 per cent footprint reduction compared to the company’s u-blox SARA-R4. The space gained can be used to host larger antennas, which can improve radio frequency (RF) performance, or to accommodate larger-size batteries.

It also has 2G fallback capability. Whenever LTE-M / NB-IoT coverage conditions are not optimal, it will keep functioning by falling back onto a 2G network. This is practical and convenient in countries where LTE-M / NB-IoT networks have yet to be fully deployed.

The module is natively designed to support GNSS (Global Navigation Satellite System) AT commands and is also ready for GNSS bundling. Its dedicated port enables easy integration with any u-blox M10-based GNSS module, for instance the u-blox MIA-M10, to improve performance and lower power consumption, said u-blox. The module can also connect to additional positioning services such as AssistNow and CellLocate.

“Since the module supports the u-blox M10 GNSS platform, customers save execution time and resources,” says Samuele Falcomer, senior product line manager, product centre cellular at u-blox.

The module’s AT commands and a dedicated I2C port can operate the GNSS core to eliminate the need to integrate additional code into the MCU. “In addition, the LEXI-R4 module offers a single SKU with global LPWA (low power wide area) coverage that simplifies logistics,” added Falcomer.

The first samples will be available by the end of Q3 2023.

u-blox provides positioning and wireless communication in automotive, industrial, and consumer markets. Its services and products let people, vehicles and machines determine their precise position and communicate wirelessly over cellular and short range networks. The company offers a broad portfolio of chips, modules, and secure data services and connectivity, to empower developers to introduce solutions for the IoT, quickly and cost-effectively. The company has headquarters in Thalwil, Switzerland and offices in Europe, Asia, and the USA.
